TECHNICAL FIELD

This disclosure relates in general to the field of electronic devices,and more particularly, to a multimodal interface.

BACKGROUND

End users have more electronic device choices than ever before. A numberof prominent technological trends are currently afoot (e.g., morecomputing devices, more detachable displays, more peripherals, etc.),and these trends are changing the electronic device landscape. One ofthe technological trends is to connect a multitude of devices to anelectronic device. In many instances, each of the devices have singlepurpose unique connectors to connect the device to the electronic deviceand one connector may not operate or function as another connector. Forexample, a universal serial bus (USB) connector is different than adisplay High-Definition Multimedia Interface (HDMI) connector. Hence,there is a challenge in providing an electronic device that allows for aunified connector that can support multiple devices.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS Example Embodiments

FIG. 1 is a simplified block diagram of an embodiment of communicationsystem 100 with a multimodal interface in accordance with an embodimentof the present disclosure. Communication system 100 can include anelectronic device 102 and one or more secondary devices 104 a-104 d.Each secondary device 104 a-104 c can include an interface 128 a-128 crespectively. In an example, one or more secondary devices may include awireless module to enable wireless communications. For example,secondary device 104 d is illustrated as including a wireless module 130a.

Electronic device 102 can include an operating system (OS) 108, aprocessor 110, memory 112, an OS policy manager (OSPM) 114, operatingregion (opregion) 116, firmware 118, a platform policy manager (PPM)124, one or more local policy managers (LPM) 126 a-126 d, and one ormore multimodal interfaces 106 a-106 d. Memory 112 can include a mailbox122. Mailbox 122 may be a buffer in memory 112. PPM 124 can include asystem host controller 120. In an example, one or more multimodalinterfaces can include a wireless module to enable wirelesscommunications. For example, multimodal interface 106 d is illustratedas including a wireless module 130 b. In another example, wirelessmodule 130 b is included in electronic device 102 and its resources canbe shared by a plurality of multimodal interfaces. Secondary device 104d can be in wireless communication with electronic device 102 usingwireless modules 130 a and 130 b.

In an embodiment, each multimodal interface 106 a-106 d can have acorresponding LPM 126 a-126 d. For example, multimodal interface 106 amay correspond to LPM 126 a, multimodal interface 106 b may correspondto LPM 126 b, multimodal interface 106 c may correspond to LPM 126 c,and multimodal interface 106 d may correspond to LPM 126 d. Eachmultimodal interface 106 a-106 d may be a multimodal interface that cansupport power transfers, directionality, and multiple input/output (I/O)protocols on the same interface. The multiple protocols may beautomatically configured to run either simultaneously or by themselveson the multimodal interface or connector without user intervention. Forexample, each secondary device 104 a-104 d may be a different electronicdevice and a single multimodal interface (e.g., one of multimodalinterfaces 106 a-106 d) may be able to support each different secondarydevice 104 a-104 d.

Elements of FIG. 1 may be coupled to one another through one or moreinterfaces employing any suitable connections (wired or wireless), whichprovide viable pathways for communications. Additionally, any one ormore of these elements of FIG. 1 may be combined or removed from thearchitecture based on particular configuration needs. Communicationsystem 100 may include a configuration capable of transmission controlprotocol/Internet protocol (TCP/IP) communications for the transmissionor reception of packets in a network. Communication system 100 may alsooperate in conjunction with a user datagram protocol/IP (UDP/IP) or anyother suitable protocol where appropriate and based on particular needs.

For purposes of illustrating certain example techniques of communicationsystem 100, it is important to understand the communications that may betraversing the communication environment. The following foundationalinformation may be viewed as a basis from which the present disclosuremay be properly explained.

Current systems typically have single purpose connectors that supportonly one specific functionality such as a display connector, an audioconnector, a power connector, etc. With users having more electronicdevice choices than ever before and a need to connect those device, whatis needed is a unified connector that supports multiple functions on asingle connector. It would be beneficial if the unified connector couldbe automatically configured and use the functionality of a multimodalconnector on a platform independent of OS or I/O protocols.

To implement a solution where an OS can communicate with connectedhardware, each connected hardware must communicate over a specificprotocol to the underlying hardware. However, this is highly undesirableas the software driver needs to be specific to the OS and also requiresthe software driver to be customized to a platform port and deviceimplementation. To enable a common solution for all OSs, a genericfirmware based interface that allows an OS to interact with differenttypes of hardware needs to be defined. The interface should not bedeveloped specific to an OS which would increase the burden on originalequipment manufacturer (OEM) enabling and negatively impacting the timeto market readiness for new technology.

A communication system that includes a multimodal interface, as outlinedin FIG. 1, can resolve these issues (and others). In communicationsystem 100 of FIG. 1, each multimodal interface 106 a-106 d can be amultimodal interface or connector that can support power transfers,directionality, and multiple I/O protocols on the same interface orconnector. The multiple protocols can be automatically configured to runeither simultaneously or by themselves on the multimodal interfaceswithout user intervention. Communication system 100 can include a set ofdata structures, commands, notifications, and state transitions (bothsoftware and hardware) to efficiently configure and operate a platformwith one or more multimodal interfaces or connectors. Communicationsystem 100 can also communicate the capabilities of a platform to an OSthat implements multimodal interfaces. I/O protocols can be configuredto operate over the same or different pins on a multimodal interfaces.

The methodology can be defined in an OS (e.g., Android™, iOS™, Linux“,OSX™, Windows™, etc.) and I/O interconnect (e.g., I2C™, I2S”, PCIe™,etc.) agnostic fashion and as the data structures used to interface withmultimodal interfaces in electronic device 102. As a result, hardwarecomponent designers, system builders, and device driver (software)developers, can develop platforms and devices with multimodal interfacesthat seamlessly interoperate with one another. For example, PPM 124 caninclude a combination of hardware and firmware and any vendor providedOS support software that provides the interface to all the multimodalinterfaces on the platform or electronic device. A specific interface(e.g., PCIe™, I2C™, etc.) is not required in order to interface with PPM124. In addition, the interface between OSPM 114 and PPM 124 is definedin such a way as to be easily implemented using any of the abovementioned interconnects or any other interconnect not mentioned above.

Using PPM 124 and OSPM 114, communication system 100 can define ageneric firmware based interface that abstracts the underlying hardware(e.g., Type C hardware), allowing the OS to access the hardware withoutknowing or understanding its specifications or intricacies. OSPM 114 isthe interaction layer from OS 108 that abstracts the underlying platformspecific hardware and is the platform agent that performs actualphysical transactions with the hardware. Communication with the hardware(e.g., secondary devices 104 a-104 d) from OS 108 begins with OSPM 114and passes through an LPM (e.g., LPM 126 a) before reaching the hardware(e.g., secondary device 104 a).

Firmware 118 may be a firmware based device policy manager that can beimplemented by OEMs irrespective of the OS they need to support or thenumber of specific ports and devices on the platform or electronicdevice 102. This allows the development effort for OEMs to be reducedand allow for an accelerated time to market for new products, devices,and features. Firmware 118 and PPM 124 can abstract the underlyinghardware from OS 108 to interact with LPM 126 a-126 d. LPMs 126 a-126 ddo the actual command level communication with a secondary device (e.g.,secondary devices 104 a-104 d) connected to a multimodal interface(e.g., multimodal interfaces 106 a-106 d).

Each multimodal interface 106 a-106 d can be an interface or connectorwith some minimal detection logic that interacts with an LPM 126 a-126 drespectively. Electronic device 102 can understand, control, orcommunicate with secondary devices 104 a-104 d through a connected LPM126 a-126 d. Each LPM 126 a-126 d can physically be part of a SOC or canseparately be on a platform concealed by other micro controllers (e.g.,an embedded controller or an integrated sensor hub). Because PPM 124provides an abstraction layer for communications between OS 108 and eachsecondary device 104 a-104 d, this allows for workarounds and bug fixesto be implemented at a platform level only without upper layer changessuch as OS layer changes.

OSPM 114 is primarily responsible for communicating, to firmware 118,any OS 108 based requests or communications to secondary devices 104a-104 d and vice versa. Firmware 118 can abstract the underlyinghardware from OS 108 and OSPM 114 by interacting with PPM 124. PPM 124is a platform specific component that maintains all (or almost all)platform and system level information on different secondary devices 104a-104 d and directly communicates with each LPM 126 a-126 d that managean individual multimodal interface 106 a-106 d. The communicationmechanism between OSPM 114 and firmware 118 can work with almost anyspecific PPM 124. Firmware 118 can be implemented in multiple ways(including ACPI, SMM, etc.) such that firmware 118 can enable runtimecommunication with OSPM 114.

Communication between OSPM 114 and PPM 124 may go through mailbox 122.Mailbox 122 can be a shared buffer in memory 112 or some other locationin a memory 112 of electronic device 102. Mailbox 122 can be a sharedmemory generic data structure that is defined in a format based oninterface specification registers for secondary devices 104 a-104 d thatdescribe the registers and pattern of access to secondary devices 104a-104 d. In a specific example, mailbox 122 can be shared memory that isdefined in a format based on the USB Type C Software Interfacespecification registers which describe the registers and pattern ofaccess to Type C hardware.

To avoid possible race condition between two successive commands from OS108 and a secondary device (e.g., one of secondary devices 104 a-104 d),when the communication between OS 108 and the secondary device is a twoway communication, mailbox 122 can be partitioned into two regions, eachaccessible only to either firmware 118 or OSPM 114. For example, mailbox122 can be partitioned as a command and response area. In an example,OSPM 114 can write a request or command from OS 108 to a secondarydevice in an OSPM 114 part of mailbox 122. PPM 124 can read mailbox 122to receive the request or command from OSPM 114. In case there is acommunication alert from the secondary device to OSPM 114, PPM 124 canupdate mailbox 122 and alert OSPM 114, which then reads mailbox 122 toprocess the cause for the alert.

System host controller 120 may be an embedded controller (EC) used inclient systems, a baseboard management (BM) controller used in serversystems, an I2C™ controller used in tablet systems, an integrated sensorhub (ISH) that may be used in long term possible solutions, or someother similar system that facilitates communications to and from PPM124. Firmware 118 can establish opregion 116 for a communication channelthat is irrespective of the type of PPM 124. For example, when there isa request detected from OSPM 114, firmware 118 can update opregion 116with the request and alert PPM 124. In one example, opregion 116 canhelp facilitate access to a shared area such as mailbox 122. Morespecifically, opregion 116 can define where the shared area is locatedin electronic device 102 so that firmware 118 can update or retrieve thedata in the shared area using access information provided by opregion116. In an illustrative example, PPM 124 can retrieve the request (e.g.,a request or communication from OS 108), process it, and communicate therequest to a secondary device (e.g., secondary device 104 a) using a LPM(e.g., LPM 126 a) and a multimodal interface (e.g., multimodal interface106 a) connected to the secondary device. Similarly, any request orcommunication from the secondary device can pass through a multimodalinterface (e.g., multimodal interface 106 a) and a LPM (e.g., LPM 126 a)and be received by PPM 124. PPM 124 can update mailbox 122 with therequest or communication and OSPM 114 may be notified of the update.OSPM 114 can retrieve the request or communication using firmware 118that in turn communicates with PPM 124 using opregion 116 and mail box122. In an example, any request or communication from the secondarydevice (or interface or LPM) is first updated in opregion 116 by PPM 124before firmware 118 writes it to mailbox 122 and is read by OSPM 114.

In a specific example, when OSPM 114 is in an idle state, OSPM 114 maybe waiting for a notification or request from OS 108, PPM 124, or someother element. From the idle state, OSPM 114 may send a command andenter into a wait for command completion state. For example, OSPM 114may send a connector status update command to PPM 124 and wait for aresponse from PPM 124. If the command was a reset PPM command, then thecommand may result in notifications being disabled from OSPM 114 and PPM124 can send a reset indicator to indicate the reset command wasreceived.

While in the wait for command completion state, if PPM 124 responds witha busy indicator, OSPM 114 can delay completion of the command andreturn to the wait for command competition state. If PPM 124 respondswith a busy indicator and OSPM 114 determines that the command needs tobe canceled, OSPM 114 can enter into a cancel present commandintermediate state, send a cancel command message, and return to thewait for command competition state.

Also, from the idle state, OSPM 114 may wait for a notification, inwhich case OPSM 114 remains in the idle state. If a connector changepending indication is set, then OSPM 114 may enter into an OPM processconnector change intermediate state. From the OPM process connectorchange intermediate state, OSPM 114 can send an associated command andenter into an OPM wait for command completion state or acknowledge theconnector change, send an acknowledgement command, and enter into a waitfor acknowledge command indicator state. After PPM 124 has sent anacknowledgement command indicator to indicate the connector change asbeing completed, PPM 124 can move from the OPM wait for acknowledgecommand indicator state to the idle state.

Using communication system 100, an OS vendor can properly interoperatewith a system that supports multimodal interfaces or connectors such asmultimodal interfaces 106 a-106 d. This can allow OS vendors andoperating hardware vendors (OHVs) to develop software and hardware thatcan interoperate seamlessly. This can also enable an original equipmentmanufacturer (OEM) or an OHV to deliver products to users and produce OSagnostic standardized hardware that will work seamlessly with variousOSs, attached third party peripherals, and even to improve thecapability of products to communicate with each other.

At 504, alocal policy manager in communication with the interface receives thedata and communicates at least a portion of the data and/or related datato a platform policy manager. For example, LPM 126 a can receive thedata from multimodal interface 106 a and communicate the data to PPM124. At 506, the platform policy manager communicates at least a portionof the data and/or related data to an interface. For example, PPM 124may communicate at least a portion of the data to firmware 118. At 508,the interface stores at least a portion of the data and/or related datain a buffer and communicates a message to an operating system policymanager that the data and/or related data has been stored in the buffer.For example, firmware 118 may store the data and/or related data inmailbox 122 and communicate a message to OSPM 114 that the data and/orrelated data has been stored in mailbox 122. At 510, the operatingsystem policy manager accesses the buffer and retrieves the data and/orrelated data.

The data may have been received from secondary device 104 athrough interface 128, may have been a result of interface 128 a beingdisconnected from multimodal interface 106 a or some other communicationor event. At 604, the local policy manager communicates the data and/orrelated data to a platform policy manager. At 606, the platform policymanager communicates the data and/or related data to an operating systempolicy manager. For example, PPM 124 may communicate the data and/orrelated data directly to OSPM 114, may communicate the data and/orrelated data to OSPM 114 using firmware 118 and mailbox 122, or maycommunicate the data and/or related data to OSPM 114 using some otherpath or means.

Turning to FIG. 7, FIG. 7 is an example timing flow diagram illustratingpossible operations that may be associated with a multimodal interface,in accordance with an embodiment. In an embodiment, an LPM 126 a sendsan alert notification to PPM 124. PPM 124 copies the alert to firmware118. In an example, PPM 124 can copy the alert to firmware 118 usingopregion 116. Firmware 118 copies the alert to mailbox 122 and firmware118 notifies OSPM 114 of the alert. OSPM 144 reads the alert in mailbox122 for information, processes the alert, and sends an acknowledgementto mailbox 122. OSPM 144 also sends a notification to firmware 118 thatOSPM 144 has placed data in mailbox 122. Firmware 118 reads mailbox 122for acknowledgement details and communicates the acknowledgment detailsto PPM 124. In an example, firmware 118 can communicate theacknowledgment details to PPM 124 using opregion 116. PPM 124communicates acknowledgement details to LPM 126 a and LPM 126 aprocesses the acknowledgement details and provides a response to PPM124. PPM 124 copies the acknowledgement response to firmware 118. In anexample, PPM 124 can copy the acknowledgement response to firmware 118using opregion 116.

Turning to FIG. 8, FIG. 8 is an example flowchart illustrating possibleoperations of a flow 800 that may be associated with a multimodalinterface, in accordance with an embodiment. In an embodiment, one ormore operations of flow 800 may be performed by one or more of OSPM 114,PPM 124, and LPM 126 a-126 d. At 802, a command is sent from a device.At 804, the system determines if the command was a reset command. If thecommand was a reset command, then a reset completed indicator isreceived by the device, as in 806.

If the command was not a reset command, then the system determines if abusy indicator was received in response to the command, as in 808. If abusy indicator was not received in response to the command, then acommand completion notification is received by the device, as in 810. At812, the command completion is acknowledged. If a busy indicator wasreceived in response to the command, then the system determines if thecommand should be cancelled, as in 814. If the command should becancelled, then a cancel command message is sent, as in 810. If thecommand should not be cancelled, then the device waits for a response tothe command, as in 816. At 810, a command completion notification isreceived and the command completion is acknowledged, as in 812.

Turning to FIG. 9, FIG. 9 is an example flowchart illustrating possibleoperations of a flow 900 that may be associated with a multimodalinterface, in accordance with an embodiment. In an embodiment, one ormore operations of flow 900 may be performed by one or more of OSPM 114,PPM 124, and LPM 126 a-126 d. At 902, a command is received at a device.At 904, the system determines if the command was a reset command. If thecommand was a reset command, then the device is reset, as in 906. At908, a reset indicator is sent.

If the command was not a reset command, then the system determines ifthe device is busy, as in 910. If the device is not busy, then thecommand is completed as in 922 and a completed command notification issent, as in 924. If the device is busy, then the system determines ifthe command is a cancel current command message, as in 912. If thecommand is a cancel current command message, then the current command iscancelled, as in 914 and a cancelled command acknowledgement is sent, asin 916. If the command is not a cancel current command message, then abusy indicator is sent, as in 918. At 920, the system determines if thedevice is busy. If the device is busy, then the system checks again tosee if the device is busy, as in 920. If the device is not busy, thenthe command is completed, as in 922 and a completed command notificationis sent, as in 924.

Turning to FIG. 10, FIG. 10 is an example simplified data structuretable 1000 illustrating possible details that may be associated with amultimodal interface, in accordance with an embodiment and is oneexample of a structure of the memory locations used to pass informationbetween OSPM 114 and PPM 124 is illustrated in table 1000 of FIG. 10. Inan embodiment, data structure table 1000 can include an offset column1002, a name column 1004, a memory location column 1006, a directioncolumn 1008, and a size column 1010. Name column 1004 can include thenames of data structures for example, version 1012, reserved 1014,connector change indication (CCI) 1016, control 1018, message in 120,and message out 1022.

Direction column 1008 can include a direction in which each memorylocation may be used. For example, PPM->OPM indicates that PPM 124 usesthe memory location to pass information to OSPM 114. The location isread only (RO) as far as OSPM 114 is concerned. Similarly OPM->PPMindicates that OSPM 114 uses the memory location to pass information toPPM 124. The location is RO as far as PPM 124 is concerned. Name column1004 can include names of example data structures that may be used incommunication system 100.

For example, version 1012 can include a version data structure. Theversion data structure can include a Binary-Coded Decimal (BCD) versionto which PPM 124 is compliant. Reserved 1014 may be a reserved area ofmemory. CCI 1016 can include a CCI data structure. The CCI datastructure can include the responses from the PPM 124 to commands sent toit by OSPM 114 as well as asynchronous status change notifications thatoccurred on multimodal interfaces 106 a-106 d. Control 1018 can includea control data structure. The control data structure can indicate thecommand to be executed by PPM 124. Message in 120 can include a messagein data structure. The message in data structure can include the datathat PPM 124 wants to send to OSPM 114. Message out 1022 can include amessage out data structure. The message out data structure can includethe data to be sent to PPM 124. The format of message in and message outdata structures can be command specific.

In addition, various commands can be sent by OSPM 114 to PPM 124 toconfigure and operate multimodal interfaces 106 a-106 d. In oneillustrative example, a command PPM reset can be used to reset PPM 124.The command PPM reset may be sent at any time by OSPM 114 to PPM 124.Upon receiving the command PPM reset, PPM 124 can perform a hard reseton each multimodal interfaces 106 a-106 d that is in communication withPPM 124. A cancel command can be used to cancel a command previouslysent to PPM 124. A connector reset command can be used to resetmultimodal interfaces 106 a-106 d. An acknowledge command completionand/or change indication can be used to communicate an acknowledgment toPPM 124 that OSPM 114 received and processed a command completion and/ora connector change indication. A set notification enable command can beused to set a list of asynchronous events that PPM 124 may sendnotifications about to OSPM 114.

A get capability command can be used to get the capabilities of PPM 124.A get connector capability can be used to get the capabilities ofmultimodal interfaces 106 a-106 d. A set operation mode can be used toset the operation mode that OSPM 114 wants for multimodal interfaces 106a-106 d. For example, set operating mode can be used to set multimodalinterface 106 a to a specific USB operating mode.

A get alternate mode can be used to determine alternate modes that asecondary device (e.g., secondary device 104 a) supports. A getconnector alternate modes supported command can be used to determine alist of alternate modes that are supported on or by multimodalinterfaces 106 a-106 d. A get current connector alternate mode commandcan be used to determine a current alternate mode that a multimodalinterface (e.g., multimodal interface 106 a) is operating in. A set newconnector alternate mode command can be used to set a new alternate modethat OSPM 114 wants a multimodal interface (e.g., multimodal interface106 a) to operate in.

A get power delivery objects (PDOs) command can be used to get a sink orsource PDO associated with a multimodal interface (e.g., multimodalinterface 106 a). A set power role command can be used to set a powertransfer direction (either source or sink) of a multimodal interface(e.g., multimodal interface 106 a). A get cable properties command canbe used to get the properties of a cable or some other type ofcommunication or data connector attached to a multimodal interface(e.g., multimodal interface 106 a). A get connector status command canbe used to get a current status (e.g., power role, data role, alternatemodes configured, etc.) of a multimodal interface (e.g., multimodalinterface 106 a).

Upon PPM 124 initialization, PPM 124 is expected to function without anyOS 108 interaction. On completion of internal initialization, PPM 124can be in a PPM Idle (notifications disabled) state. PPM 124 may notnotify OSPM 114 of any activity until OSPM 114 enables one or morenotifications via a set notification enable command. On successfulcompletion of the set notification enable command PPM 124 can transitionto a PPM idle (notifications enabled) state. The only commands PPM 124is required to process in the PPM idle (notifications disabled) stateare set notification enable commands and PPM reset commands.

In an example operational model, OSPM 114 can send at most one commandat a time to PPM 124. Once a command is sent, OSPM 114 must wait untilPPM 124 completes the current command before sending the next command.PPM 124 can notify OSPM 114 when it completes the command if the commandcompleted notification is enabled. The only exceptions to the onecommand rule are a cancel command and a PPM reset command. A PPM resetcommand may be sent by OSPM 114 at any time. The cancel command shouldonly be sent by OSPM 114 when OSPM 114 wants to cancel an outstandingcommand that OSPM 114 had previously received a PPM busy response. Also,PPM 124 may send only one notification at a time to OSPM 114. PPM 124can wait until OSPM 114 acknowledges the notification (due to anasynchronous event) before sending the next notification.

On reception of a command that is not a cancel command or a PPM resetcommand, PPM 124 can execute the command or set a busy indicator in aCCI data structure if PPM 124 is busy or PPM 124 will take more than apredetermined amount of time (e.g., 10 ms) to complete the command. Uponexecution of the command, PPM 124 can set the CCI data structure andoptionally update a status and message in data structure. If a commandcompleted notification was enabled by OSPM 114 then PPM 124 can notifyOSPM 114 of the completed command.

On receiving a cancel command, PPM 124 can cancel the currentoperation(s) it was performing or drop or ignore the cancel request ifPPM 124 was not currently processing a command. If PPM 124 can completethe cancel command successfully, PPM can update the CCI data structurewith the cancel completed indicator set to one. If the command completednotification was enabled by OSPM 114 then PPM 124 can notify OSPM 114 ofthe completed command.

On receiving a PPM reset command, PPM 124 can disable all notifications,reset itself and set the reset completed indicator in the CCI datastructure, and transition to a PPM idle (notifications disabled) state.OSPM 114 can poll for the reset completed indicator in the CCI datastructure. When an asynchronous event occurs on one or more of theconnectors, PPM 124 can update the CCI and status data structures andnotify OSPM 114 if the corresponding notification was enabled by OSPM114. Once OSPM 114 is notified of either a command completion and/or anasynchronous event OSPM 114 can read the CCI and optionally the statusdata structures and acknowledge the notification via the acknowledgecommand completion and/or change indication command. If the event was anasynchronous event, then OSPM 114 can send any other commands it needsto get details on the asynchronous event.
